What is Blue Light?

The blue light is simply the color all around us. It's important to know that blue light represents about a third of all visible light.

So what's the news?

In recent years we have discovered that blue light regulates the sleep and wake cycles, boosting alertness, elevating your mood and increasing feelings of well-being.

It seems all good, what I need to know?

The bad news is that Blue Light can be artificial and not only natural.

Blu Light today is present in your life than never before: LED TV, smartphones, computer monitor, tablets, ebook readers and all devices with LED screens.

Can Blue Light cause permanent damage?

An Harvard study revealed that the over-exposure of the blue light affect your circadian rhythm.

Sleep suffers.

If you use devices that emit blue light in the evening/night, your body thinks that is daytime. Potentially this cause sleepless nights.

Not only: they may cause Digital Eye Strain.

What is Digital Eye Strain?

American Optometric Association says:

“Digital Eye Strain describes a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader and cell phone use. Many individuals experience eye discomfort and vision problems when viewing digital screens for extended periods. The level of discomfort appears to increase with the amount of digital screen use.”

The most common symptoms associated with Computer Vision Syndrome (CVS) or Digital Eye Strain are:

- Eyestrain
- Headaches
- Blurred Vision
- Dry eyes

What can I do to prevent all of this?

There are many solutions, but the ones that work for sure are two:

1) Use “Night Shift” mode in your devices if available. Apple created this mode because they have confirmed that blue light disrupt your sleep. 

The main problem is the colors of your display are shiftsto warmer colors, this change your perception and can't be always valid (think about if you work with Photoshop)

2) Use blue-blocking glasses: this solution avoid the problem of the colors changement, so you can work perfectly and avoid eye problems.
